Benzmac, Steve, someone, please share how an idle control valve fails.
I know that when the idle air valve fails, it generally sticks open. Could it still move when twelve volts are applied, yet still be bad? When they get old/worn, can they get out of phase/sync with the volts delivered from the computer?
Would monitoring the milliamps tell you if its bad, assuming that it is still moving to twelve volts?
Thanks for sharing.
